In Germany 2 Claims.

This invention relates to a cutting table arrangement for cuttingmachines for waffles and the like. In waflie cutting machines of knownkind the arrangement is such that the pile of waffle sheets is movedsuccessively in paths at right angles to one another by reciprocablefeeding devices, and during this movement is cut up by cutting framesstanding at right angles to these paths, the sheets first being cut intostrips and then the strips into pieces of the desired size.

Before the next pile of waflle sheets can be cut up the two feedingappliances must be brought back again into their initial position.Consequently special idle strokes must be interposed.

The object of this invention is to obviate, partially or completely,these idle strokes upon the feeding paths, to save the time occupied bythese idle strokes and to increase the output or efficiency of themachines. For this purpose a cutting table is arranged either at eachend of the stroke of one of the feeding appliances, for instance of thefeeding appliance serving for moving the sheets that have been cut upinto strips, or else at each end of the stroke of each of the feedingappliances.

The simpler form of construction, in which one cutting set is providedat each end of the stroke of one of the feeding appliances only, forinstance the second one, which serves to move the sheets that have beencut into strips, is illustrated in plan in Figure 1 of the accompanyingdrawing.

The form of construction in which one cutting set is arranged at eachend of the stroke of each feeding appliance is illustrated, likewise inplan, in Figure 2.

The feeding appliance itself, the type of construction of the cuttingframe, and the other parts of the cutting machine form no part of thepresent invention, protection being exclusively claimed for thearrangement of the cutting tables, by which the idle strokes that takeplace in the known cutting machines are partially or wholly eliminatedand replaced by working strokes, in consequence of the arrangement ofcutting sets at both ends of the stroke of one or both of the feedingappliances.

In the form of construction shown in Figure 1, a strip-shaped feedingappliance or slat a, is moved by a pulling or pushing spindle b, andserves for feeding a pile of wafiie sheets d along a table 0 towards aset of cutters e, here constructed as a wire-cutting frame. The pile ofsheets is thus cut into strips while traversing this first path andbrought on to a central supporting March 1, 1935 plate 1. The feedingappliance or slat a returns to its initial position. From the centralsupporting plate the material passes to one of the removal tables n orW, according to the position of a feeding device 9 which is moved by aspindle h, 5 and in traversing this second path, the strips are cut intopieces of the desired size by a set of cutters k, when fed on to thetable n, and by a set of cutters m when fed on to the table n Ac cordingto the drawing the removal tables n and n must now be cleared to enablethem to receive the next pile of strips fed from the central supportingplate and cut up into square by cutters k or m.

In the form of construction illustrated in Figure 2, the same appliance,which is only arranged on one side of the supporting plate a in theconstructional form of Figure 1, is now arranged on both sides. At eachmovement of the feeding appliance or slat i from one end of the stroketo the other a pile 3 locatedupon the supporting plate 2 is cut intostrips by a set of cutters 4 or 5, and is brought on to a central plate6 or 1, from which, by the movement of a feeding appliance or slat 8 onone side and slat 9 on the other side of the supporting plate 2, thecutting of the strips into pieces is effected in one direction or theother by one of the sets of cutters If], ll, 12, i3. From the removaltables l4, l5, IE or ii the pile of cut pieces is then taken away at theproper time, so that the removal tables will be free for thenext pile.

Sheets of soap, or piles of soap sheets or other material in similarform admit of being cut into pieces in the same manner as piles ofwaffle sheets by using the arrangement of cutting tables hereinbeforedescribed.

It is not essential that the feed paths should be at right angles to oneanother, and should serve for cutting rectangular sheets, as illustratedin the drawing, but they can also be extended obliquely in relation toone another and cut up sheets of other forms.

What I claim is:-

1. A double cutting machine for thin slabs comprising a centralsupporting plate, a side table attached thereto, spaced vertical cuttersalong the 'border line between the side table and said plate and meansfor feeding a thin slab from the side table onto said central platethrough said outters; a receiving table along opposite edges of saidplate, spaced vertical cutters along the respective border lines betweensaid central table and the receiving tables and other means for feedinga thin slab from said central table alter- 55 5 pieces when passinganother cutter from said. plate to one of said receiving tables.

2. A double cutting machine for waflies in thin slabs in accordance withclaim 1 in which said feeding means each consists of a narrow slatreaching across the side table and the central plate respectively and ascrew engaging said slat in such a manner as to reciprocate the slatback and forth along the side table and the central 5 platerespectively.
